iSPECIFICATION formingpart of Letters Patent No. 700,899, dated May 27,1902.

Application filed September 11 1901. Serial No.74,989- (No model-l ToaZl whom it may concern.-

Be it known that 1, JOHN H. CLARK, a citizen of the United States,residing at Uhrichsville, in the county of Tuscarawas and State of Ohio,have invented certain new and use ful Improvements in Trolley-\Vheels;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the figures of referencemarked thereon, in which-'- Figure 1 is a side elevation. Fig. 2 is anedge view. Fig. 3 is a section of the wheel and its head Fig. i is adetached view of one of the axle-boxes. Fig. 5 is a view, showing aportion of one member of the head and illustrating one of the axle-boxesplaced in proper position. Fig. 6 is a similar view showing the axle-boxand retaining-plate removed.

The present invention has relation to trolley-wheels; and it consists inthe different parts and combination of parts hereinafter described, andparticularly pointed out in the claim.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, 1 represents the shank of an ordinarytrolley-pole, which shank is provided with the bifurcated end composedof the two members 2 and 3, which members are spaced one from the othera distance sufficient to allow room for the trolleywheel 4. Theperiphery of the trolley-wheel 4 is of the usual construction and isprovided with an ordinary groove 5 for the reception of the usualtrolley-wire.

The trolley-wheel 4 is provided with the integral axle 6, or, ifdesired, the axle may be formed separate and connected to thetrolley-wheel 4 in any convenient and well-known manner; but to carryout the object and purpose of the present invention the axle 6 mustnecessarily rotate with the trolley-wheel and not remain at rest, or, inother words, the trolley-wheel 4: is not to revolve upon the axle.

Upon the outer sides of the members 2 and 3 are located chambers 7,which chambers are formed by the spherical flanges 8. Upon the innerfaces of each of the members 2 and 3 of the trolley-wheel head properare formed the grooves 9, and of course the grooves 9 are locateddirectly opposite each other. The grooves 9 are for the purpose ofreceiving and holding in proper position the axle-boxes 10,which-axle-boxes are formed of such a length that they will span thechambers 7, by which arrangement the ends of the axle 6 are'located inthe chambers 7 substantially as illustrated in Fig. 3.

For the purpose of securely holding the boxes 10 in fixed position andalso preventing any accidental displacement of the boxes the retainingbars 11' are provided, which retaining-bars are preferably seated intorecesses 12, which recesses are formed upon the upper sides of the headmembers 2 and 3, and said plates held in fixed position by lug-bolts 13or their equivalents. The upper ends of the boxes 10 are provided withthe beveled ends 14 and are beveled at such an angle that theywill beparallel with the retaining-bars 11 when said retaining-bars are broughtor placed into their fixed position.

It will be understood that by providing the removable retaining-bars 11they can be taken ofi, after which the boxes 10 are free to be removed,together with the wheel 4 and its axle, this object being desired forthe purpose of making repairs or for any other purpose when it isdesired to remove the trolley- Wheel 4 from its head proper.

WVithin the chambers? is located what is commonly called waste or otheroil-absorbing substance, and in use oil is applied to the waste throughthe oil-holes 15 and 16, a sulficient amount of oil being applied at asingle timeto thoroughly saturate the waste. By this arrangement theaxle of the trolley-wheel will remain properly lubricated for aconsiderable length of time, thereby doing away Having fully describedmy invention, What grooves and over the openings and means I claim asnew, and desire to secure by Letters Patent, is

The combination of a trolley-wheel pro- 5 vided with an axle rotatablewith said trol- Icy-Wheel, a trolley-head consisting of members spacedone from the other and each of the members provided with a chamber,there being a groove located in the inner faces of 10 the head membersand communicating with the chambers, axle boxes located in the forholding the axle-boxes in fixed position, substantially as and for thepurpose specified.

In testimony that I claim the above I have 15 hereunto subscribed myname in the pres ence of two witnesses.

JOHN H. CLARK.
